log4net is a tool to help the programmer output log statements to a variety of output targets. log4net is a port of the excellent log4j framework to the .NET runtime. We have kept the framework as similar to the original log4j as possible while taking advantage of new features in the .NET runtime. For more information on log4net see the features document.


log4net is hosted at sourceforge.net. For more information see:

Documentation for each release is available online. Each release contains a full copy of the source, examples, build environment and documentation.
